This invention relates to an improvement in dish washing machines.

The principal object of the inventionis to provide a machine of thischaracter in which the motive power to operate the same is supplied bythe flow of water simultaneously utilized for the cleaning of the dishesand in which the rotating speedof the dish supporting means ismaintained sufliciently low to insure the proper cleaning of the dishes.

The invention also contemplates the utilization of an improved drivingmechanism which obviates any manual assistance 1n starting the deviceand which insures a substantially constant rotating speed of the dishcarrier. I

A further object of the invention'is to provide a machine of thischaracter which is operable by a relatively small pressure of water andwhich obviates the need of regulation or adjustment after the machinehas been started.

Another object of the invention is to provide a portable dish washingmachine so constructed that it may be placed in the sink and connectedto the faucet thereof by means of a flexible tubing. If desired themachine may also be maintained in any fixed position in the kitchen andsuitably connected for 0- operation to a source of water supply.

' A further object is to provide a machine which is simple and positivein operation and in which an improved construction for the rotatabledish carrier is utilized to maintain the dishes in a position whichinsures a passage of water over their entire surface and therebyfacilitate their proper cleaning.

The invention further includes other objects, advantages and novelfeatures of design, construction and arrangement hereinafter moreparticularly referred to and which will be apparent from theaccompanying drawin s in which I have illustrated the preferred orm ofthe invention.

Referring to the drawings, and more particularly to Figs. 1 and 3, Iprefer to illustrate the embodiment of the invention as employed withina suitable casing of any desiredshape or dimension. As hereinillustrated the casing is constructed in the form of a box having a topwall 10, bottom wall 11, side walls 12 and 13 and front and rear walls14 and 15 respectively.

The bottom wall 11 is provided with a suitable opening 16 fordischarging the soiled water from the interior of the casing. An Lconnection 17 may be associated with the discharge opening 16 so that aflexible tubing can be connected to the same if desired. The front wall14 of the casing is open, as indicatedat 18, to permit the insertion ofthe utensil supporting baskets on the rotatable carrier within themachine as will be hereinafter more particularly described.

A door 19 suitably hinged on the side of the wall forms a closure forthe opening 18 when the device is in operation. A window 20 is locatedin the door 19 so that the operator may observe the extent to which themachine has washed the dishes.

Referring more particularly to Figs. 2 and 3, a cross bar 21 is suitablyconnected to the inwardly extending lugs on the upper por tion of thecasing. .The cross bar 21 is adapted to form a support for the drivingmechanism of the machine. An off-set portion of the cross bar 21 isindicated at 22, the purpose ofwhich will be hereinafter moreparticularly described.

To assure rigidity and firmness in the support 'the cross bar 21-integrally includes forked arms 23 and 24 extending from one end thereofas clearly shown in Fig. 2. A hollow annular ring member 25 is suitablyfixed in position on the cross bar 21 and arms 23 and 24 thereof.

A connection 26 associated with said ring 25 has an overheadhorizontally disposed pipe 27 connected thereto. The pipe 27 isconnected to a vertical water supply pipe 28 within the casing whichextends substantially to the bottom wall 11. A T connection 29 unitesthe same with a horizontally disposed pipe 30 extending through anopening in the side wall 12 of the casing. Any suitable means, such'as aflexible tubing, may be utilized to connect the end of the pipe 30 to aconvenient source of water supply.

Centrally located within said annular ring,

25 is a disk member 31 having a plurality of blades extending therefrom,one of which is indicated at 32. The multi-blade disk 31 is rotatablyassociated with the fixed annular member 25 by means of a shaft 33suitably j'ournalled in the top wall 10 of the casing as indicated at 34and in an opening in an extending portion 35 of the cross bar 21.

A plurality of nozzles are suitably located on the annular member 25,one'of which is indicated at 36, for directing the flow of water againstthe blades of the disk 31 to rotate the same. As herein illustrated thenozzles arearranged in groups about the periphery of the member 25 insuch a manner that the power transmitted by the flow of water therefromwill exert a continuous effect against each. blade of the diskthroughout its'circular travel. Because of this distribution of efiortsimultaneously operative against the entire number of blades utilized,the device can be successfully operated by a relatively small pressureof water. As soon as the starting inertia of the rotatable dish supportis overcome, a constant speed is maintained without the need ofregulation. A further material advantage is obtained inasmuch as manualassistance by the operator in starting the device is obviated.

A rotatable basket support is indicated at 37, the upper portion ofwhich is journalled in the off-set portion 22 of the cross bar 21 asindicated at 38 by means of a shaft 39 suitably connected thereto. Thelower portion of the support 37 is journalled in the bottom wall 11 ofthecasing as indicated at 40. The parallel shafts 33 and 39 areconnected by means of a reduction gearing, the pinion on the shaft 33being indicated at 41. The pinion located on the shaft 39 is indicatedat 42. This gearing is located within the off-set po tion 22 of thebasket 21 to be out of contact with the other moving parts of thedriving mechanism. By the use of this reduction gearing the basketsupport rotates at a sufficiently reduced speed to insure a thoroughcleaning of the dishes. .While I have illustrated the preferred form ofthe driving mechanism, it is obvious that various modifications andalterations in the form of construction herein used may be resorted towithout departing from the nature and spirit of the invention.

The basket support 37 is preferably constructed in the form of acircular frame including verticall disposed rods connecting the upperand lower portions thereof, two of the rods being indicated at 43 and44. Each rod is suitably provided with a set of inwardly disposed hookmembers as indicated at 45 and 46 and form a fastening means by whichthe dish carriers may be firmly mounted therein. The rods 43 and 44 areplaced sufficiently far apart to enable the dish supporting members tobe placed on the hooks within the basket support. As herein illustratedthe basket support 37 provides an upper and lower position formaintaining the dish carriers. that the basket support could beconstructed to maintain any desired number of dish carriers.

Spray nozzles 47 and 48 are connected to the vertical supply pipe 28 andadjacent to the upper and lower positions of the dish support baskets.The lower surface of the annular ring member 25 and pipe 27 may beprovided with a number of pin hole openings therein, one of which isindicated at 49 for directing an overhead spray of water upon the dishcarriers.

Also extending from the T member 29 is a suitably located horizontalpipe 50 on the bottom wall 11 of the casing. This pipe maybe providedwith a number of pin hole openings, one of which is indicated at 51 fordirecting an upward flow of water against the lower portion of therotatable basket support. As herein illustrated, a single verticallydisposed pipe 28 is located within the casing. If desired, a pluralityof such pipes may be utilized in corresponding parts of the casingwithout departing from the nature and spirit of the invention.

Referring more particularly to Fig. 4, a modified form of the rotatablebasket support 37 is illustrated. In this form of the backet the lowercircular rim 52 thereof is elevated to a relatively higher position fromthe bottom wall 11 of the casing than that illustrated in Fig. 3. Thelower frame work is formed in a conical shape tapering to an apex atwhich point an integral bearing 53 is located. The use of such a basketsupport member facilitates a freer movement of the soiled water in thebottom of the casing in flowing out of the discharge opening 16.

Referring more particularly to Figs. 5 and 6, the preferred form of dishcarriers or baskets is illustrated. In this construction the dishcarriers comprise basket sections as indicated at 54 and 55, the crossbars on the It is obvious, however,

upper portion thereof forming maintaining means forholdingthe dishes ina proper position therebetween. The bases upon which the dishes rest areindicated at 56 and 57. The cross bars, two of which are indicated at 58and 59, in Fig. 6, are spaced farther apart on one side of the carrierthan on the other. The dishes are consequently maintained in the basketin a-fan like formation. A portion readily placed on adjacent sides of.the basket support 37 on the hooks and 46 provided therefor. The basketsections 54 and 55 are constructed to provide a suitable clearance asindicated at 63 between their adjacent portions when in position in thesupport 37. This facilitates the ready insertion or removal of thecarriers from the support without interfering with one another.

Referring to Fig. 7, a valve structure 64 is located onthe horizontalpipe 30 for controlling communication to the same with a reservoirindicated at 65 for liquidsoap or other suitable cleaning solution. Thereser voir and valve are preferably situated adjacent to and within theside wall 12 of the casing. The valve handle for the valve is situatedso that the operator can readily manipulate the same when the door 19 isopen. In the operation of the machine the dish carriers or baskets 54and 55 are first loadedv and then placed in position within the support37. The valve 64, controlling the flow of cleaning solution, is thenopened to any desired degree depending upon the condition of the soileddishes. After-the door 19 is closed, the end of the pipe 30 is suitablyconnected to the source of hot water supply. lhe flow of water andcleaning solution enters the pipes 27 28, 50 and annular ring member 25and simultaneously dischargesfrom the spray nozzles 47 and 48, pin holeopenings 49 and 51 and from the nozzles 36 of the member 25. Themulti-blade disk 31 is rotated by means'of the fiow'of water impingingagainst the blades. This rotation is transmitted to the basket support37 through the J reducing gears 41 and 42. The relatively slow rotationof the dish carriers on the support 37 and the fan like arrangement ofthe dishes facilitates the passage of cleaning solution and water overthe entire surface of thedishes as they pass adjacent the spray nozzles47 and 48. The soiledwateris discharged through the opening 16. Afterthe dishes have been thoroughly cleaned the valve 64 is turned ofl andthe apparatus is suitably connected to a source of cold water supply torinse the dishes and clean the YaIIOHS discharge outlets.
